Effect of Tooth Mousse on Streptococcus Mutans in the Plaque of High Caries-risk Preschool Children: A Triple-Blind, Randomized Clinical Trial.

Purpose: Control of Streptococcus mutans can prevent caries in high-risk preschool children. The purpose of this study was to assess the effect of casein phosphopeptide amorphous calcium phosphate (CPP-ACP) on Streptococcus mutans in the plaque of high-risk preschool children.

Methods: A triple blind, randomized, controlled clinical trial included 40 healthy three- to five-year-olds with at least one white spot lesion.

Effectiveness of 2 chemomechanical caries removal methods on residual bacteria in dentin of primary teeth.

Purpose: The purpose of this study was to evaluate the effectiveness of 2 chemomechanical caries removal methods-Carisolv and Papacarie-on the residual cariogenic bacteria in the dentin of primary teeth vs traditional hand excavation.

Methods: Forty-five primary teeth were divided into 3 groups, according to the caries removal method used. Carious dentin samples were taken, then all softened dentin was removed, and a second sample was taken when the cavities were clinically caries-free, All teeth were filled with composite resins.
